TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the plugin MCP server error.

Guidance

• The errors indicate a missing GITHUB_PERSONAL_ACCESS_TOKEN environment variable, which is required for the MCP server to function correctly.
• To mitigate the MaxFileReadTokenExceededError, consider using offset and limit parameters to read specific portions of the file instead of reading the whole file.
• Verify that the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is set correctly by checking the system environment variables or the project's configuration files.
• The Lock acquisition failed error may be related to multi-process scenarios, but it is not directly related to the GITHUB_PERSONAL_ACCESS_TOKEN issue.

Notes

The provided errors suggest that the issue is related to the MCP server configuration and file reading limits. However, without more information about the project's configuration and dependencies, it is difficult to provide a more specific solution.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the plugin MCP server error. This should allow the MCP server to function correctly and prevent the mcp-config-invalid errors.
